Now all functions, which were "contained" in anoter one are moved to seperate modules. This allows for strict interface checking and debugging

This routine has been contained in a subroutine. It has been moved to a module and and renamed to "single_hh_trafo_real" to make it's intention more clear

All variables (real, integer, complex) are now declecared with the appropiate kind statement. The definition of the kind types is done in src/mod_precision.f90 To ensure interoperability with C, the kind types are decleared via iso_c_binding to C variables

The Fortran variable declerations "variable type*[4,8,16]" is non Fortran standard. It might cause problem in the future. Furthermore, the usage of Fortran and C togehther is more clean if variables are defined according to C variable types. This is done, now for all the test programs

Previously, the list of modules used or defined by a source file was assumed to be the same regardless for which target the file was used (except for library/non-library compilation). Now, every target has its own list of defined and required modules per source file

Will be added in the subsequent commit as a 'subtree' from upstream

This commit does not change the interfaces defined in ELPA_2015.11.001 ! All functionality is available via the interface names and definitions as in ELPA_2015.11.001 But some new interfaces have been added, in order to unfiy the references from C and Fortran codes: - The procedures to create the ELPA (row/column) communicators are now available from C _and_ Fortran with the name "get_elpa_communicators". The old Fortran name "get_elpa_row_col_comms" and the old C name "elpa_get_communicators" are from now on deprecated but still available - The 1-stage solver routines are available from C _and_ Fortran via the names "solve_evp_real_1stage" and "solve_evp_complex_1stage". The old Fortran names "solve_evp_real" and "solve_evp_complex" are from now on deprecated but still functional. All documentation (man pages, doxygen, and example test programs) have been changed accordingly. This commit implies a change in the API versioning number, but no changes to codes calling ELPA (if they have been already updated to the API of ELPA_2015.11.001)

For the library functions which are accessible by the user man pages decribing the Fortran and C interface exist: -get_elpa_row_comms -solve_evp_real , solve_evp_complex -solve_evp_real_2stage, solve_evp_complex_2stage For the "service binary" print_available_elpa2_kernels, also a man page exists. TODO: extend man pages to test-binaries, or do not install test-binaries

The Rechenzentrum Garching (RZG) has been renamed into the Max Planck Computing and Data Facility (MPCDF). This is reflected now in the adapted headers. In the near future, all references to the ELPA webside and the ELPA email will also be adapted.

The user functions of ELPA are now documented with doxygen tags. At the moment the interface of ELPA 2015.11.001 is decribed. The documentation has step by step to be implemented for all functions and test programms.

As in a previous commit for elpa1.F90, for automatic generation of documentation elpa2.F90 has been splitted in two files, in order to have a lean, easy-to-understand user interface: elpa2.F90 the visible user functions, which provide the library calls. The usage is the same as before elpa2_compute.F90 all internal routines, which are used by ELPA2, but which are never called external of the library by a user. These functions are now "hidden" in the module elpa2_compute, which is used by ELPA2. The procedures in elpa2_compute.F90 are identical to the ones in elpa2.F90 before this split commit. The only -- but quite a lot of them -- changes are intendation changes.

This variables, do not have to be global, they can be parsed along internally in ELPA. Removing them makes debugging more easy and the public interface more lean

Current fix does as much blocking as possible, which should be beneficial from both a compute and communication point of view. Additionally, a second possible fix was added which just calls the blocked version if the local matrix has a sufficient size. This might create smaller and more messages at scale.

For some matrix/block size combinations the real case of ELPA2 crashes, e.g: mpiexec -n 1 ./elpa2_test_real 50 50 32 leads to an error message ** On entry to DGEMM parameter number 3 had an illegal value and a crash. This only seems to happen with matrix size smaller than 64*64. he code path responsible for this has been identified, but the problem tself is not yet solved! The part of the code, which causes these crashes, has been switched on as default by Intel in commit fe63372d. The rest of the commit fe63372d seems to be fine, and is performance critical. As an intermediate step, the responsible code path is switched off again as default, this will be changed again once the underlying root cause has been solved.

Intel (thanks, especially A.Heinecke from Intel) there exists an optimized version of ELPA with AVX2 support. This merge includes all the optimizations done by Intel plus some smaller changes which were necessary to incorperate these modifications.
